IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters Patent and making part o! thesame.

'Be it known that we, LEONARD S'rnnLINe and 'l. W. WILLSON, both of thecity, county, and State of New York, have invented a new and usefulImproveinent in Lamps, of which the following is a full,

clear, and exact description, reference being'had to the accompanyingdrawing'forming part of this specification, and which representsasectional elevation of a lamp in bracket form constructed in accordancewith our invention. y

'Our invention, while applicable to variouskinds of lamps orilluminating coutriva'uces, including table lamps, chandeliers employingany number of burners, and bracket lights of different kllldS,'Wil1 herebe de-' scribed as applied to a bracket designed to be used against awall or other suitable support.

Although, like a certain kind of lamp, theflamc is supplied with oil orfluid at one side of the reservoir by means of a siphon-shaped tube, itessentially differs therefrom in the extension of the one leg of saidtube through the fluid in the reservoir, and to or near the bottom ofthe latter, and in a suitable arrangement of an independent wick-holderor chamber, whereby the oil or fluid is supplied to the latterexclnsively by siphonic action, and i not by capillary attraction,aswhere the tube only connects with the top of the reservoir, and is notprojected through the fluid therein, and whereby thebent supply-pipe ortube is ope'rative withoutthe insertion ot'a wicktherethrough, andotheradvantages are obtained.

Referring to the accompanying drawing- A represents the .oil orfluid-reservoir, carried by an upright back or frame-piece, B, tofacilitate itsbeing hung against the wall or other support.

0 is a siphon-tube, the onelegof which is arranged to project throughthe cap or top of the reservoir, and down, through the oil or fluid, toor near the bottom of the reservoir, where, on its being suitably perfoirated or formed at its lower end, as at a a, to estab lish communicationwith the fluid, it may rest, to form a support for the siphon in turningit, shoifld it be desirable to make the bracket a swinging one.

The other or outer end or leg of the siphon O is connected with awick-holder or chamber, 1), of suitable depth and size to hold a fiat orother-shaped wick, I), and copious supply of oil or old thereto.

This chamber 1) carries a suitable burner, and is arranged so that itsbase cxtends'to within a short distance of the bottom of the reservoirA.

By this construction and arrangement of the parts there is notroublesome insertion of the wick within orthrough the siphon-tube, butit is or may be restricted exclusively to the independent holder D, thatalso forms an enlarged fluid-chamber, for the perfect saturation of thewick, while the tube 0 is 'clear to operate as a siphon, its projectionbeyond the top of the reservoir and through the fluid, down to or nearthe bottom of the reservoir, securing such action for it and insuringits retention of fluid at all times, 'as

well as a perfect siphonic action, as contradistinguished from acapillary'one, so long as the level of the fluid in the reservoir A iseven with or above the bottom of the chamber D, which, being arranged asdescribed, efi'ects, purely on a siphonic principle of action, thesupply of the whole or greater portion of the fluid in the reservoir tothe outside wick b, that, as before ob served, is altogetherindependent, so'far as its situation or arrangement is concerned, alikeof the reservoir A and siphon-tube O, and which may readily be insertedor removed, .as in the case of anprdinary lamp, within or from itsholder and secondary fluid-reservoir D, on taking oli the top of thelatter.

By means of the back or frame-piece B, the siphonbracket or wholedevice, as thus constructed, may readily be hung against a wall, and itstwo reservoirs A and D retained in a vertical position.

In conclusion, it may be well to note, in connection with the operationof our improved lamp, whether in bracket-form or otherwise, that, whenthe wick'b has absorbed all the oil or fluid in the chamber D, and theoil or fluid in the reservoir A has, by the action of the siphon'G,reached a depth or level corresponding with the bottom of the chamber orwick-holder D, there will still remain in the siphon and reservoir acertain amount of fluid not accessible to the wick, since the bottom ofthe wick-holder D is always at a small distance above the bottom of thereservoir A. The furtherac'tion of the siphon-tube is consequentlyundisshown and described.
